Linguistic Characteristics of Suicidal Patients in the Emergency Department

February 13, 2017 updated by: Children's Hospital Medical Center, Cincinnati

Linguistic Characteristics of Suicidal Patients in the ED (Emergency Department)

The purpose of this study is to determine whether patients who have a high risk for serious suicide behavior will demonstrate a speech pattern that has a relationship to language patterns found in suicide notes.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

In an average week the CCHMC Emergency Department (ED) evaluates 40 patients with suicidal behavior. Currently, there is no systematic method for assessment of suicide risk in these patients and often, emergency department staff are required to make judgments about the disposition of these patients without a full understanding of the patient's risk for another serious suicide attempt. This pilot project involves experts in child psychiatry, biomedical informatics, and emergency medicine to collect pilot data for developing a method to estimate the risk of serious suicidal behavior based on computational linguistics.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

13 years to 17 years (CHILD)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Sampling Method

Non-Probability Sample

Study Population

CCHMC suicidal and non-suicidal adolescents

Description

Inclusion Criteria for Suicidal Subjects:

  • Subjects age 13 years 0 months to 17 years, 11 months old
  • Admission to CCHMC ED, psychiatric units, or medical units with suicidal behavior or attempt
  • The patient and legal guardian must understand the nature of the study and be able to comply with protocol requirements. The legal guardian must give written informed consent and the youth, written assent.
  • English is spoken as the primary language in the home

Inclusion Criteria for Non-Suicidal Subjects:

  • Subjects age 13 years 0 months to 17 years, 11 months old
  • Admission to CCHMC ED with no current or no history of suicide ideation/attempt/gesture
  • No past or current history of a major mood disorder
  • No history of death by suicide in first-degree relatives
  • The patient and legal guardian must understand the nature of the study and be able to comply with protocol requirements. The legal guardian must give written informed consent and the youth, written assent.
  • English is spoken as the primary language in the home

Exclusion Criteria for Suicidal Subjects:

  • Any serious, unstable medical illness or clinically significant abnormal laboratory assessments that would adversely impact the scientific interpretability or unduly increase the risks of the protocol
  • Level of consciousness precludes consent and research assessments
  • Unable to assent because of severe mental retardation or incapacitating psychosis

Exclusion Criteria for Non-Suicidal Subjects:

  • Any current or past suicide attempts
  • Any serious, unstable medical illness or clinically significant abnormal laboratory assessments that would adversely impact the scientific interpretability or unduly increase the risks of the protocol.

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.

Study Major Dates

Study Start

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.

Primary Completion (ACTUAL)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
